The real repair is to have the vehicle serviced by a Bentley dealer. The other option is as follows…
Press and hold the trip button
While doing this, turn the ignition key into the on position
Let go of both, and you will see the words “service reset” on the drivers instrument panel screen
Now press the silver knurled roller switch “OK” on the right side of the steering wheel controls, by the menu button. This will confirm the request.

With the ignitionkey off, press and hold the trip button
while doing this, turn the ignitionkey to the on position
The driver’s instrument panel screen will now read “service reset.”
Now press the silver knurled knob on the right side of the steering wheel controls, this will confirm the operation.
